Comprehensive Study Guide on Climatology, Cell Biology, and Marine Zoology

Climatology and Greenhouse Gases

  • Hand Galing pe: Preliminary notes regarding greenhouse gas dynamics.
  • Primary Greenhouse Gases: The Following are the primary greenhouse gases and their specific heat-trapping capabilities, including CO2CO_2.
  • Ice Age: Defined as a period of global cooling during which sheet ice covers the poles. These cycles occur approximately every 200×106200 \times 10^{6} years (200 million years).
  • Greenhouse Effect: The biological and atmospheric phenomenon of absorbing and removing/rerunning heat within the atmosphere.
  • IPCC (2005/2007): The Intergovernmental Panel on Climate Change concluded in its 2007 (and 2005) reports that human activity is the primary cause of modern climate change.
  • Short-Term Drivers of Climate Variation:
    • Volcanoes: They eject sulfur into the upper atmosphere, which can lead to periods of cooling.
    • Solar Output: Natural fluctuations in the energy emitted by the sun.
  • Long-Term Drivers of Climate Variation:
    • Milankovitch Cycles: Changes in Earth's orbit and tilt that affect long-term climate patterns.
    • Plate Tectonics: The movement of Earth's crustal plates.
  • Mitigation and Solutions:
    • Conserving energy and reducing pollution.
  • Mauna Loa Standard Trend: Reference to the standard trend in data (specifically CO2CO_2 levels) measured at the Mauna Loa observatory.

Cellular Biology and Energetics

  • RNA Transcription: Process happens in the nucleus to keep RNA away from potentially damaging agents.
  • Mitochondria: Organelles enclosed by a double membrane that produce significant amounts of ATPATP by burning glucose.
  • Ecological Niche: The specific site where a new population lives and reproduces; it defines the role and position of a species within its environment.

Marine Invertebrates: Porifera, Cnidaria, and Ctenophora

  • Phylum Porifera (Sponges):
    • Structure: Organized around water canals for filter feeding ("sponge foods").
    • Competition: Sponges compete for space with corals and bryozoans.
  • Phylum Cnidaria:
    • Body Plans: Typically exhibit one of two body plans: Polyp or Medusa.
    • Class Scyphozoa: Known as "true jelly," they exist primarily in the medusa stage.
    • Class Cubozoa (Box Jelly): Found in tropical waters; they are strong-swimming and highly predatory.
    • Class Anthozoa: Includes sea anemones and corals.
    • Tentacles: Contain specialized stinging structures known as nematocysts.
  • Phylum Ctenophora (Comb Jellies):
    • Anatomy: Unlike Cnidarians, they lack stinging cells (nematocysts).
    • Locomotion: They swim primarily using rows of cilia.

Platyhelminthes and Ichthyology

  • Phylum Platyhelminthes (Flatworms):
    • Symmetry: Bilaterally symmetrical.
    • Anatomy: Possess eyespots (ocelli) that allow for the distinction between the back (dorsal), head (anterior), and front.
  • Ichthyology (Study of Fish):
    • Benthic Fish: Refers to bottom-dwelling species.
    • Buoyancy: Many fish utilize swim bladders to maintain buoyancy in the water column.
    • Trophic Levels: Fish occupy various roles including high trophy (predators), herbivores, and scavengers.
    • Scales: Certain groups, such as cartilaginous fish, possess placoid scales.
    • Environmental Adaptations: Fish thrive in various wood/water environments and exhibit specialized features for their specific niches.
